Copernicus: Mewn haf o danau gwyllt gwelwyd dinistr a chofnodwyd allyriadau o amgylch Hemisffer y Gogledd



The Copernicus Atmosphere Monitoring Service has been closely monitoring a summer of extreme wildfires across the Northern Hemisphere, including intense hotspots around the Mediterranean basin and in North America and Siberia. The intense fires led to new records in the CAMS dataset with the months of July and August seeing their highest global carbon emissions respectively.

Gwyddonwyr o'r Gwasanaeth Monitro Atmosffer Copernicus (CAMS) have been closely monitoring a summer of severe wildfires which have impacted many different countries across the Northern Hemisphere and caused record carbon emissions in July and August. CAMS, which is implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the European Commission with funding from the EU, reports that not only large parts of the Northern Hemisphere were affected during this year’s boreal fire season, but the number of fires, their persistence and intensity were remarkable.

As the boreal fire season draws to a close, CAMS scientists reveal that:

  • Dry conditions and heatwaves in the Mediterranean contributed to a wildfire hotspot with many intense and fast developing fires across the region, which created large amounts of smoke pollution.
  • July was a record month globally in the GFAS dataset with 1258.8 megatonnes of CO2 released. More than half of the carbon dioxide was attributed to fires in North America and Siberia.
  • According to GFAS data, August was a record month for fires as well, releasing an estimated 1384.6 megatonnes of CO2 globally into the atmosphere.
  • Arctic wildfires released 66 megatonnes of CO2 rhwng Mehefin ac Awst 2021.
  • Estimated CO2 emissions from wildfires in Russia as a whole from June to August amounted to 970 megatonnes, with the Sakha Republic and Chukotka accounting for 806 megatonnes.

Scientists at CAMS use satellite observations of active fires in near-real-time to estimate emissions and predict the impact of resulting air pollution. These observations provide a measure of the heat output of fires known as fire radiative power (FRP), which is related to the emission. CAMS estimates daily global fire emissions with its Global Fire Assimilation System (GFAS) using the FRP observations from the NASA MODIS satellite instruments. The estimated emissions of different atmospheric pollutants are used as a surface boundary condition in the CAMS forecast system, based on the ECMWF weather forecast system, which models the transport and chemistry of atmospheric pollutants, to predict how global air quality will be affected up to five days ahead.

The boreal fire season typically lasts from May to October with peak activity taking place between July and August. In this summer of wildfires, the most affected regions were:

Môr y Canoldir


Many nations in eastern and central Mediterranean suffered the effects of intense wildfires throughout July and August with smoke plumes clearly visible in satellite imagery and CAMS analyses and forecasts crossing the eastern Mediterranean basin. As southeast Europe experienced prolonged heatwave conditions, CAMS data showed daily fire intensity for Turkey reaching the highest levels in the GFAS dataset dating back to 2003. Following the fires in Turkey, other countries in the region went on to be affected by devastating wildfires including Greece, Italy, Albania, North Macedonia, Algeria, and Tunisia.

Fires also hit the Iberian Peninsula in August, affecting vast parts of Spain and Portugal, especially a large area near Navalacruz in the Avila province, just west of Madrid. Extensive wildfires were also registered east of Algiers in northern Algeria, CAMS GFAS forecasts showing high surface concentrations of the polluting fine particulate matter PM2.5.


While the Sakha Republic in northeastern Siberia typically experiences some degree of wildfire activity every summer, 2021 has been unusual, not just in size but also the persistence of high-intensity blazes since the beginning of June. A new emissions record was set on 3rd August for the region and emissions were also more than double the previous June to August total. In addition, the daily intensity of the fires reached above average levels since June and only began to subside in early September. Other areas affected in Siberia have been the Chukotka Autonomous Oblast (including parts of the Arctic Circle) and the Irkutsk Oblast. The increased activity observed by CAMS scientists corresponds with increased temperatures and decreased soil moisture in the region.

Gogledd America

Large scale wildfires have been burning in western regions of North America throughout July and August affecting several Canadian provinces as well as the Pacific Northwest and California. The so-called Dixie Fire which raged across northern California is now one of the biggest ever recorded in the state’s history. Resulting pollution from the persistent and intense fire activity affected the air quality for thousands of people in the region. CAMS global forecasts also showed a mixture of smoke from the long-running wildfires burning in Siberia and North America travelling across the Atlantic. A clear plume of smoke was seen moving across the north Atlantic and reaching western parts of the British Isles in late August before crossing the rest of Europe. This happened as Saharan dust was travelling in the opposite direction across the Atlantic including a section over southerly areas of the Mediterranean resulting in reduced air quality. 

Mark Parrington, Senior Scientist and wildfire expert at the ECMWF Copernicus Atmosphere Monitoring Service, said: “Throughout the summer we have been monitoring wildfire activity across the Northern Hemisphere. What stood out as unusual were the number of fires, the size of the areas in which they were burning, their intensity and also their persistence. For example, the wildfires in Sakha Republic in northeastern Siberia have been burning since June and only started receding in late August although we have been observing some continuing fires in early September. It’s a similar story in North America, parts of Canada, the Pacific Northwest and California, which have been experiencing large wildfires since the end of June and beginning of July and are still ongoing.”

“It is concerning that drier and hotter regional conditions - brought about by global warming - increase the flammability and fire risk of vegetation. This has led to very intense and fast-developing fires. While the local weather conditions play a role in the actual fire behaviour, climate change is helping provide the ideal environments for wildfires. More fires around the world are anticipated in the coming weeks, too, as the fire season in the Amazon and South America continues to develop,” he added.

Copernicus is a component of the European Union’s space programme, with funding by the EU, and is its flagship Earth observation programme, which operates through six thematic services: Atmosphere, Marine, Land, Climate Change, Security and Emergency. It delivers freely accessible operational data and services providing users with reliable and up-to-date information related to our planet and its environment. The programme is coordinated and managed by the European Commission and implemented in partnership with the Member States, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), EU Agencies and Mercator Océan, amongst others.

ECMWF operates two services from the EU’s Copernicus Earth observation programme: the Copernicus Atmosphere Monitoring Service (CAMS) and the Copernicus Climate Change Service (C3S). They also contribute to the Copernicus Emergency Management Service (CEMS), which is implemented by the EU Joint Research Council (JRC). The European Centre for Medium-Range Weather Forecasts (ECMWF) is an independent intergovernmental organisation supported by 34 states. It is both a research institute and a 24/7 operational service, producing and disseminating numerical weather predictions to its member states. This data is fully available to the national meteorological services in the member states. The supercomputer facility (and associated data archive) at ECMWF is one of the largest of its type in Europe and member states can use 25% of its capacity for their own purposes.

Mae ECMWF yn ehangu ei leoliad ar draws ei aelod-wladwriaethau ar gyfer rhai gweithgareddau. Yn ogystal â phencadlys yn y DU a Chanolfan Gyfrifiadura yn yr Eidal, bydd swyddfeydd newydd sy'n canolbwyntio ar weithgareddau a gynhelir mewn partneriaeth â'r UE, fel Copernicus, wedi'u lleoli yn Bonn, yr Almaen o Haf 2021.

Mae Is-lywydd Gweithredol Timmermans yn cynnal Deialog Newid Hinsawdd Lefel Uchel gyda Thwrci



Derbyniodd yr Is-lywydd Gweithredol Timmermans Weinidog Amgylchedd a Threfoli Twrci Murat Kurum ym Mrwsel am ddeialog lefel uchel ar newid yn yr hinsawdd. Profodd yr UE a Thwrci effeithiau eithafol newid yn yr hinsawdd yn ystod yr haf, ar ffurf tanau gwyllt a llifogydd. Mae Twrci hefyd wedi gweld yr achos mwyaf erioed o 'snot môr' ym Môr Marmara - gordyfiant o algâu microsgopig a achosir gan lygredd dŵr a newid yn yr hinsawdd. Yn sgil y digwyddiadau hyn a achoswyd gan newid yn yr hinsawdd, bu Twrci a’r UE yn trafod meysydd lle gallent hyrwyddo eu cydweithrediad yn yr hinsawdd, wrth geisio cyflawni nodau Cytundeb Paris. Cyfnewidiodd yr Is-lywydd Gweithredol Timmermans a’r Gweinidog Kurum farn ar gamau brys sydd eu hangen i gau’r bwlch rhwng yr hyn sydd ei angen a’r hyn sy’n cael ei wneud o ran torri allyriadau i lawr i sero-net erbyn canol y ganrif, a thrwy hynny gadw’r nod 1.5 ° C. o Gytundeb Paris o fewn cyrraedd. Fe wnaethant drafod polisïau prisio carbon fel maes o ddiddordeb cyffredin, gan ystyried sefydlu System Masnachu Allyriadau yn Nhwrci sydd ar ddod a diwygio System Masnachu Allyriadau’r UE. Roedd addasu i newid yn yr hinsawdd hefyd yn ymddangos yn uchel ar yr agenda ynghyd ag atebion ar sail natur i wrthsefyll newid yn yr hinsawdd a cholli bioamrywiaeth. Gallwch wylio eu sylwadau cyffredin yn y wasg yma. Mwy o wybodaeth am y Deialog Lefel Uchel yma.

Etholiad yr Almaen: Mae streicwyr newyn eisiau mwy o weithredu ar newid yn yr hinsawdd



Mae grŵp o bobl ifanc yn nhrydedd wythnos streic newyn yn Berlin, gan honni nad yw pleidiau gwleidyddol yr Almaen yn mynd i’r afael yn ddigonol â newid yn yr hinsawdd cyn etholiad cyffredinol y mis hwn, yn ysgrifennu Jenny Hill, Newid yn yr hinsawdd.

Mae’r protestwyr - rhwng 18 a 27 oed - wedi addo parhau â’u streic newyn nes bod y tri ymgeisydd blaenllaw sy’n cystadlu i gymryd lle Angela Merkel yn cytuno i gwrdd â nhw.

Mae yna awyrgylch ddarostyngedig ymhlith y pebyll bach a'r baneri wedi'u paentio â llaw yn agos at Gangellor yr Almaen ym Merlin.


Mae'r chwe pherson ifanc sydd wedi bod ar streic newyn am fwy na phythefnos yn dweud eu bod yn teimlo'n wan.

Yn 27, Jacob Heinze yw'r hynaf o'r protestwyr yma (dywed y trefnwyr fod pedwar o bobl eraill wedi ymuno â'u streic newyn i ffwrdd o'r gwersyll). Mae'n siarad yn araf, yn amlwg yn ei chael hi'n anodd canolbwyntio, ond dywedodd wrth y BBC, er ei fod yn ofni canlyniadau ei "streic newyn amhenodol", mae ei ofn o newid yn yr hinsawdd yn fwy.

"Dywedais eisoes wrth fy rhieni a fy ffrindiau bod siawns na fyddaf yn eu gweld eto," meddai.


"Rwy'n gwneud hyn oherwydd bod ein llywodraethau yn methu ag achub y genhedlaeth ifanc o ddyfodol sydd y tu hwnt i ddychymyg. Sy'n erchyll. Rydyn ni'n mynd i wynebu rhyfel ynglŷn ag adnoddau fel dŵr, bwyd a thir ac mae hyn eisoes yn realiti i llawer o bobl yn y byd. "

Gyda llai na phythefnos i etholiad cyffredinol yr Almaen, mae Jacob a'i gyd-brotestwyr yn mynnu bod y tri ymgeisydd blaenllaw i gymryd lle Angela Merkel fel Canghellor yr Almaen yn dod i siarad â nhw.

Streicwyr newyn dros bolisi hinsawdd yn Berlin, 2021

Gellir dadlau mai newid yn yr hinsawdd yw'r mater etholiad mwyaf yma. Mae gwleidyddion yr Almaen wedi cael eu dylanwadu gan brotestiadau stryd fawr gweithredwyr newid hinsawdd ifanc yn ystod y blynyddoedd diwethaf ond mae llifogydd marwol yr haf hwn yng ngorllewin y wlad hefyd wedi canolbwyntio pryder y cyhoedd.

Er hynny, dywedwch y streicwyr newyn, nid oes yr un o’r prif bleidiau gwleidyddol - gan gynnwys y blaid Werdd - yn cynnig mesurau digonol i fynd i’r afael â’r broblem.

"Nid oes unrhyw un o'u rhaglenni yn ystyried y gwir ffeithiau gwyddonol hyd yn hyn, yn enwedig nid y perygl o dipio pwyntiau (newidiadau hinsoddol mawr na ellir eu gwrthdroi) a'r ffaith ein bod yn agos iawn at eu cyrraedd," meddai'r llefarydd Hannah Luebbert.

Mae hi’n dweud bod y protestwyr eisiau i’r Almaen sefydlu cynulliad dinasyddion, fel y’i gelwir - grŵp o bobl a ddewiswyd i adlewyrchu pob rhan o gymdeithas - er mwyn dod o hyd i atebion.

"Mae'r argyfwng hinsawdd hefyd yn argyfwng gwleidyddol ac efallai'n argyfwng yn ein democratiaeth, oherwydd mae'r sefydlu gydag etholiadau bob pedair blynedd a dylanwad mawr lobïwyr a buddiannau economaidd yn ein seneddau yn aml yn arwain at y ffaith bod buddiannau economaidd yn bwysicach na ein gwareiddiad, ein goroesiad, "meddai Ms Luebbert.

"Nid yw lobïwyr yn dylanwadu ar gynulliadau dinasyddion o'r fath ac nid gwleidyddion yno sy'n ofni peidio â chael eu hailethol, dim ond pobl sy'n defnyddio eu rhesymoledd."

Golygfa o wersyll gweithredwyr hinsawdd ger adeilad Reichstag ar Fedi 12, 2021 yn Berlin, yr Almaen.
Dywed y streicwyr newyn nad oes yr un o’r ymgeiswyr yn gwneud digon i atal trychineb hinsawdd

Dywed y streicwyr newyn mai dim ond un o ymgeiswyr y Canghellor - Annalena Baerbock o’r blaid Werdd - sydd wedi ymateb, ond iddi siarad â nhw dros y ffôn yn hytrach na chwrdd â’u galw am sgwrs gyhoeddus. Mae hi wedi apelio arnyn nhw i ddod â'u streic newyn i ben.

Ond mae'r grŵp - sy'n denu cyhoeddusrwydd cynyddol - wedi addo parhau, er eu bod yn cydnabod trallod eu teuluoedd a'u ffrindiau.

Er hynny, meddai Jacob, mae ei fam yn ei gefnogi.

"Mae ofn arni. Mae hi'n ofnus iawn, ond mae hi'n deall pam fy mod i'n cymryd y camau hyn. Mae hi'n crio bob dydd ac yn galw bob dydd ac yn gofyn i mi onid yw'n well stopio? Ac rydyn ni bob amser yn dod i'r pwynt lle rydyn ni'n dweud na, mae'n angenrheidiol parhau, "meddai.

"Mae'n wirioneddol angenrheidiol deffro pobl ledled y byd."
